Where Does the Water Flush in Mobile Toilets?
The location and disposal method of water flushing in mobile toilets vary depending on the type, with the following main scenarios:
For water-flush and non-water-flush suction-type mobile toilets, they are equipped with a water-flushing device inside, and the water tank is usually placed at the top of the toilet. After the user finishes defecating, the water-flushing device is activated, and the water flow flushes the excrement into the sewage tank located at the bottom of the toilet. This type of mobile toilet does not require connection to external water supply and drainage pipes. It relies on its own water tank and sewage tank to complete the flushing and storage of waste, making it suitable for places without water supply and drainage facilities, such as outdoor event venues and construction sites. When the sewage tank is nearly full, a suction device is needed to extract and transport the sewage away for disposal.
Conventional water-flush mobile public toilets require connection to water supply and drainage pipes. In terms of sewage disposal, it can be achieved through manual operation or automatic sensing. After the user presses the flush button or triggers the automatic sensing device, the water flow flushes the excrement away, and the sewage flows through the pipes to a septic tank or municipal sewer network. Sewage discharged into the septic tank undergoes a certain sedimentation and fermentation process to reduce the concentration of waste and the content of harmful substances; while sewage discharged into the municipal sewer network enters the city's sewage treatment system for more comprehensive and in-depth treatment to meet emission standards before being discharged or reused.
Mobile public toilets with a water-storage sewage disposal system also use a water-flushing method, but they discharge the waste into a storage tank. A water level monitoring device is installed inside the toilet. When the sewage in the toilet reaches a preset water level, the flushing device automatically activates, and a strong water flow flushes the waste into the storage tank. This design ensures that waste does not need to be frequently cleaned for a period of time. When the storage tank is full, a specialized transport vehicle is used to transport the sewage in the storage tank away for disposal.
